1. A transmission power control method in a cellular communication system including a plurality of cells, a plurality of base stations respectively arranged in respective of said plurality of cells, mobile stations located within said cells, and control station provided in common for said plurality of base stations and transmitting control instruction including a balance adjustment period for balance adjustment of transmission power to respective of said mobile stations from said base stations,
wherein assuming that a frame number of transmission frame to said mobile station is CFN and said balance adjustment period is Nperiod frame, each base station comprises a step of starting said balance adjustment from the frame of the frame number CFN to be mod (CFN, m×Nperiod)=0 (m being a natural number) in response to reception of said control instruction; and
a step of restarting said balance adjustment from the frame of the frame number CFN to be zero, in each base station.
